No. Items to check and commands Action
4 When the user logs in to the console
(RS-232C), the LEDs do not light
with the normal brightness
(automatic operation is disabled). Use the
show system
operation command to check the
information displayed for
Brightness mode


normal
displayed:
LED operation is set to normal brightness. Check the setting
of the
system port-led trigger
configuration
command.
If
console
is not set in the
system port-led trigger
command, the console is not specified as the trigger for
automatic operation. Specify the console as the trigger for
automatic operation.

Other than above:
Check the configuration.
3.17.2 Power saving scheduling is disabled
If a problem occurs in scheduling power saving, perform the check procedure described in
the following table.
Table 3-34 Problems in power saving scheduling, and action to take
No. Items to check and commands Action
1 The Switch does not enter sleep
mode at the scheduled time. Check whether a user who has logged in (via serial cable or
Telnet) to the Switch used configuration command mode.
If there was such a user, save the settings and exit configuration
command mode.
Check whether
action disable
is set for the scheduled time
range (
schedule-power-control time-range
).
If it is set, change the setting to
action enable
and save the
setting.
2 After the sleep period ends, the
Switch does not run with the
specified configuration. When the Switch enters sleep mode on a schedule, any
configuration that has not been saved to that point is discarded.
Set the configuration again and save it by using the
save
command.
3 Sleep mode needs to be temporarily
canceled. Hold down the RESET button on the Switch for at least three
seconds until all LEDs on the front of the Switch turn on.
Note that the schedule-disabled mode is set after the sleep mode
is canceled. The Switch will automatically enter schedule-enabled
mode when the scheduled time range expires and a normal time
range begins.
4 After the forced cancellation of sleep
mode, the Switch enters sleep
mode again after startup. When the wake-up option (
schedule-power-control
wakeup-option
) is set, briefly pressing the RESET button for
less than three seconds does not trigger the forced cancellation of
sleep mode.
To forcibly cancel sleep mode, hold down the
RESET button until
all LEDs on the front panel of the Switch turn on.
5 When the wake-up option is set,
sending WOL packets to the port
configured to detect the reception of
WOL packets fails to cancel sleep
mode. 1. Make sure that the wake-up option is configured.
2. Specify the MAC address of the Switch as the MAC address
of WOL packets. If you specify the MAC address of the port,
the WOL packets will not be recognized as the packets for
which the wake-up option is configured.
